You built your product, put it on server, and it flew like a rocket. Now you need to move to larger scale, but how ? How to go from here ? Deploying software isn't always the first thing on developers mind, while they work on some software. However as you start moving to larger scale your deployment process can make you or break you. It comes with pain and cruel truth of how good your deployment process really is. Join me while I address pain, issue and problems of deploying software on Large Scale. I will talk about some known approaches and their pro's and con's. Also I will share some tips and tricks into making deploying software on large scale easier. All of this come from my personal experience while working on this type of systems.
